SPECIFICATION forming part of Letters Patent No. 674,666, dated May 21,1901.

Application filed January 1d,1899. Serial No. 702.119. (N model.-

To all whom it may concern.-

Be it known that I, JOHN C. BLEvNEY,acitizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Motor-Driven Vehiclesand Means for Regulating the Movements Thereof; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to characters of reference marked thereon,which form a part of this specification.

The objects of this invention are to enable the motorman or driver ofthe vehicle to more perfectly control the movements of the latter; tofacilitate the work of reversing the direction of movement of thevehicle or increasing or diminishing the speed of the same;

- to secure a simple construction and one requiring less power on thepart of the motorman to secure a change of movement; to securea moredirect transmission of power from the piston ol' the motor to the wheelsof the vehicle; to secure a greater variety of adj ustments by whichvarious changes of speed are accomplished; to secure a more positivetransmission of power from the motor stationed upon the springs of thevehicle to the axle and wheels of the vehicle; to more uniformly andexactly take up the looseness in the chain or other connections, due tothe action of the body of the vehicle and motor on thesupporting-springs; to secure a construction occupying a smaller amountof space within the vehicle, and to secure other advantages and results,some of which may be referred to hereinafter in connection with thedescription of the working parts.

The invention consists in the improved power transmitting and speedregulating means for motor-driven vehicles and in the arrangements and-combinations of parts of the same, all substantially as will behereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like characters ofreference indicate corresponding parts in each of the several views,Figure l is a plan of the motor and transmitting and governing meansembodying my invention. Fig. 2 is a side elevation of the same. Fig. 3is a side view showing a modification of construction. Fig. 4 is asection on line as. Fig. 5 is an end elevation in detail of a certainregulating-arm and connections for regulating the speed of the vehicle,and Fig. 6 is a side view of the same. Fig. 7 is a sectional detail of acertain friction sprocket-wheel arranged upon a power-shaft of thedevice. Figs. 8 and 9 are detail perspective views of meansfor-attaching certain connecting rods or bars to a belt or flexiblestrap. Fig. 10 is a side view of a certain clutch and connections. Fig.11 is a section of the same, taken at line as; and Figs. l2, l3, 14, 15,16, 17, and 18 are detailed views of portions of said clutch, which willbe hereinafter more fully described. Fig. 19 is a side view in detail ofa certain rocker and cooperating parts, and Fig. 20 is a section of thesame on line 2'. I

In said drawings, a indicates the floor or body of a wheeled vehicle ofany suitable construction. This vehicle-body is ordinarily arranged uponsprings attached to the axle of the wheels upon which the vehicletravels, the said springs a permitting a limited freedom of vibration ofthe vehicle-body independent of the movement of the axle, as will be.understood. Upon the said floor or body a is bolted or otherwisesecured a bed plate or frame 1), adapted to move with the body a on thesaid springs, and upon said bed plate or frame F) are arranged theseveral working parts, the said bed plate or frame being provided withsuitable studs or supports to receive said working parts. Upon saidbedplate are cast or otherwise formed the motorcylinders o c, in whichare operated pistons, (not shown,) by means substantially as heretoforedescribed by me in my prior application filed December 29, 1896, SerialNo. 617,372. Said pistons are connected by means of suitable rods (notshown) to arms d of an oscillating shaft 6, said shaft being arranged inhearings or boxes f, attached to the bed-plate 19, contiguous to saidcylinders. At one end of the said oscillating shaft is arranged orformed a slideway g at right angles to the axis of said shaft, and insaid slideway is arranged a slide h, provided near its upper end with apin t', which projects in a line parallel with the axis of theoscillating shaft and is adapted to receive the connecting-rod 7. Abovesaid pin 7; and at the lower extremity of the said slide hare suitableconnections k for a chainl or other flexible connection adapted to causesaid slide to move longitudinally in its slideway. Said chain alsooperates a brake device, as hereinafter described. To operate said slidelongitudinally in connection with the chain, I employ a sprocketwheel m,Figs. 1, 2, and 3, arranged on a handshaft n,in connection with ahand-wheel o,said hand-wheel being turned with the sprocketwheel ineither direction to cause a raising or lowering of the slide it in itsslideway g,- the said chain being arranged over idle pulleys p 19, Figs.1 and 6, in suitable bearings q, Fig. 6, formed on the slideway as nearto the axis of the oscillating shaft as convenience will permit. Otheridle pulleys 13 may be employed to change the direction of the chain orconnection, as .convenience or the style or character of the vehicle mayrequire. In lieu of the hand-wheel 0 I may employ a simple hand-crank orother device convenient to be grasped by the hand and secure anoperation of the sprocket-wheel m and chain. By this construction itwill be evident that by turning the hand-wheel 0 in one direction theslide h will be raised in its slideway and the pint will-be thrownupward away from the axis of the oscillating shaft 6, so that thereciprocations of the pin will be increased in distance of movement, thegreater the distance of said pin from said center of movement of theoscillating shaft the greater being the distance of oscillating movementof said pin i with the slide 72,, as will be evident.

While I prefer to operate the chain or flexible connection Z by means ofa sprocketwheel, itis evident that I may produce a draft upon the sameby other means. For example, I can dispense with the sprocket-wheel mand apply a handle directly to the chain, and thus effect a movement ofthe slide.

To secure an easy movement and reduce the friction on the chain, 1 havearranged in the chain,near the sprocket-wheelspp,swiveljoints 5, Fig. 6,whereby the chain is adapted to accommodate itself to the variouschanges in direction due to the rocking of the bar or slide 71. with theoscillating shaft, as will be hereinafter described. Should I employ arope or leather connection, thesesWivel-joints will become unnecessary;but I prefer a metal chain, as there will be less chance for stretching.By reversing the hand-shaft o the chain will force the slide it in theoscillating slideway downward, and the pin 2' will be brought close tothe center of movement of said oscillating shaft, and when the said pinarrives at the axial center of said shaft 6 it is evident that said pinwill have no reciprocating action, but will simply move with theoscillating shaft in said center and effect no operation of theconnecting-rod j, now to be described. The said connecting-rodj ispivoted upon the pin z'and extends forward therefrom and is pivotallyconnected to an eccentric crank-arm t, formed upon a sector it andpivoted at 'v. Said sector is provided with segments u u, to which aresecured the opposite ends of a strap 3. The arms '6 extend laterallyalittle beyond the plane of the segments u u, as indicated in Fig. 20,and thus the connecting-rod j will not interfere with the movements ofthe strap, as will be evident upon reference to Fig. 1. As theconnectingrod j is reciprocated by means of the slide of the rocking armor bar, the sector is also given an oscillating or reciprocatingmovement, and this movement is transmitted to the belt or band 3. Thesaid band is arranged over idle pulleys 4 4:, and at the upper part ofsaid band or belt 3 the same is formed into a loop or what approximatesa loop, as indicated in Fig. 2 at 5. To form said loop, the said band isturned over a third idle pulley 6, arranged in bearings on an arm 7 ofthe pivotal beam or frame 13, the said pulley v6 being adjust able bymeans of an adjusting-screw 8 in any suitable manner. The portions 8181, Fig. 2, of the belt, forming the upper and lower sides of the loop,move in opposite directions when the belt is operated by the sector to,and to the said parts 81 81 are connected the connecting-rods 9 9 bymeans of suitably-formed pieces 10 11. (Shown in detail in Figs. 8 and9.) The said connecting-rods 9 9 lie side by side a little way apart andon each side of the strapthree inches, more or less-aud are givenlongitudinal reciprocations by the belt or band 3, as described, and attheir forward ends,opposite those by which they are attached to thebelt, are provided with connections 12, by means of which they areattached to independent clutches, such as I will later proceed todescribe, said rods 9 and connect-ions being operated alternately toeffect an alternating clutching action of the two clutches. By means ofthe flexible strap 3 power is transmitted without producing noise orvibration, such as more positive metallic connections would produce.

The strap 3, with its idle pulleys 4t 4 6 and the clutch mechanismshereinafter described, is in the preferred construction arranged uponthe pivotal frame 13, of which the arm 7 is a part, the said frame 13being pivoted at 14 upon studs or supports 15, attached to or forming apart of the bed-plate a.

By means of the pivotal frame 13 the powershaft 16 and the clutchingmechanisms connecting therewith are permitted to move independent of thebed-plate Ct, the movements being controlled or governed by the stay161. The power-shaft-carrying end of said frame is held by said stay 161at a given distance from the axle, the axle and power-shaft beingpivotally connected to said stay. A spring 17 counterbalances the weightof the powershaft and its connections, relieving the axle ofthe weightthereof. The said frame which carries the power-shaft consists of twovertical plates 131 131, of irregular shape in side elevation, the saidplates at their ends opposite those having the arms 7 being providedwith transverse horizontal rods or bolts 18, having collars 181, bymeans of which the said plates are held apart and in proper verticalposition relative to one another. The said bolts extend laterally beyondthe planes of the said plates 131, where they are provided with supports19 19 for boxes 20, in

which last the said power-shaft 16 has itsbearings. Upon the saidpower-shaft 16, between the plates 131 131, is arranged a clutchwheel 21and at opposite sides of said clutchwheel loose sleeve 22 for operatingthe clutch mechanism, the said collars being shown in detail in Figs.and 11. Also on said powershaft 16 is arranged a sprocket-wheel 23,which is arranged between friction-disks 241 242, the saidsprocket-wheel 23 being loose upon said powershaft and adapted to beclutched thereto by means of the said friction-disks, as will behereinafter more fully described. By means of the loose sprocketwheel orpulley and friction-disks the pulley will be allowed to slip underextreme stress, such as might be produced in the event of the vehiclestriking a telegraph-pole or the like obstacle, and thus damage bybreakage may be avoided. This device also permits a sudden reversal ofthe movement of the vehicle. The power is transmitted to the wheel 250of the vehicle from the said sprocket-wheel 23 by means of a chain 25and sprocket-wheel 251 or in any suitable manner.

To operate the clutch-wheel fastened upon the power-shaft 16continuously by means of the reciprocating shaft and connections withthe clutches by means that are simple and compact, I have provided inconnection with the connecting-rods 9 9 clutch devices, (shown moreclearly in Figs. 10 to 18,) in which 26 is the clutch-dog, pivotedloosely upon the connecting-rod 9 by means of the pivotal bolt 27, thesaid dog being provided at one side with bosses 28 28, between which theflanges 201 of the clutch-wheel 21 are arranged, the said clutch-dogs261 being provided, preferably,

with steel contact-teeth 29 to secure a more positive holding contactwith the clutchwheel. The clutching-dogs 26 are pivoted upon arms orextensions 221 of the sleeve 22, the said arms 221 being provided withsuitable perforations to receive the pins 261. The said clutching-dogsare limited in their pivotal movements on the pivots 261 by Wheel-likestops 30 of peculiar construction, the said stops being pivoted uponpins 33 on the arms 221 of the sleeves, the said wheel-like stops lyingwithin openings 34 of said arms and being adjustable in their relationto the clutching-dogs, whereby the said clutching-dogs are enabled tosecure reverse movements, as will be hereinafter described. The saidstops each comprise a cog-wheel or pinion 31, at the opposite sides ofwhich are formed flanges 32 32, Figs. 8 to 16, the said flanges beingnotched at points 321, Fig. 1 1, in their peripheries to permit alimited lateral movement of a tooth or finger 262 of the clutch dog 26,the said notches, however, not being opposite or in correspondence orboth in a line parallel with the axis of the said stop 30, but being atdifierent points with respect to the periphery of the said stop.

To secure the desired reverse movement, I have provided sliding racks35, suitably arranged in slideways formed in the sleeves 22 in linesparallel with the axes of said sleeves 22, the said racks being operatedin said slideways by means of shifting-collars 36.

When I desire to secure a change in the movement of the vehicle, 1operate the shifting-collar and rack to cause a partial rotation of thepivotal stop upon its axis, whereby the notch 321 lying in coincidencewith the tooth 262 will be thrown out of such coincidence and the secondnotch in the opposite flange Will be brought into such coincidence. Thiswill cause a change in the limits of movement of the dog 26, and whereasbefore the oscillations and reciprocating actions of the said dog inconnection with the connecting-rod 9 caused a movement of theclutch-Wheel in one direction from the center position the said movementwill now be changed to move oppositely from said central position andproduce a reverse action. This will be more perfectly understood uponreference to Figs. 16, 17, and 18. In Fig. 17 the tooth 262 lies in thegroove 322, out of coincidence with either of the notches 321 of theflanges 32, and thus the clutch-dogs are prevented from biting theflange of the clutchwheel, and the connecting-rods 9 and dogs, in makingtheir reciprocations, will be ineffective in producing rotary-motion ofsaid clutch- Wheel. By operating the rack and rotating the stop in onedirection from the said central position last described theclutching-dog will be free to give a limited oscillation from saidcentral position in one direction only, the stop 262 being permitted topass back and forth into and from the notch 321 with which it is incoincidence. The parts are so related that this movement of theclutchingdog causes the clutch tobite the flanges of the clutch-wheel asit moves in one directionthe forward direction, for examplethus causinga step-by-step rotation of the clutchdog in such direction. By movingthe rack in the opposite direction from the center the notch in theopposite flange will be brought into coincidence, as indicated in Fig.18, in which case the pivoted stop will be permitted to oscillate fromits center of movement into the second notch 321, which will cause abiting by the dog only upon the return movement of said dogin itsreciprocating action with the connecting-rods 9. This will produce amovement of the clutch-wheel in the reverse direction. The shiftingstop-collars 36 36 are operated simultaneously by suitable shiftingmeans, so that the dogs which work alternately are shiftedsimultaneously to operate in opposite directions, one dog operating thewheel while the other is making its return movement, so that the saiddogs will one after the other bite the clutch-wheel and thus effect acontinuous movement of said clutch-wheel in the desired direction.

- The momentum of the carriage serves to effeet a regular and smoothmovement, so that the step-by-step actions are not perceptible to therider to any greater extent than the step-by-step movement of a horse.

The shifting devices for the collars 36 are shown in Fig. 1. Theshifting-sleeves are operated simultaneously, as before described, inthe preferred construction, by means of a connecting-rod 37, connectingrings 38, arranged in the groove of the shifting-collar,

which connecting-rod 37 is operated, preferably, by levers 39 and 40 andhandle 11 in any suitable manner.

To brake the movements of the vehicle, I employ brake devices, which arepreferably in connection with .the chain Z, which latter is providedwith acollar or equivalent device 95, adapted to engage the arm of alever 96, the last being adapted to tighten the strap 97 and produce africtional engagement of the same with a brake-wheel 98 on the axle ofthe vehicle. The arrangement of strap 97 and lever 96 may be such as iscommonly employed in braking operations. When the chain is brought toposition to produce an axial coincidence of the pin 2' and oscillatingshaft e and the motor is thus rendered inoperative, the collar on saidchain will be in position to produce the braking action, as will beunderstood.

I am aware that various modifications and changes may be made inihe'construction of the devices without departing from the spirit orscope of the invention, and I do not wish to be understood as limitingmyself to the positive terms employed in describing the inventionillustrated.

As an example of the changes which may be made I have shown the variedconstruction of Figs. 3 and i, in which I dispense with the use of acounterbalancing-weight and employ modified means for producing thestepby-step movements of the clutch-Wheel. In this modification thesector it is of a different form. It is operated by the connecting-rodj, as in the construction first described; but the connections arevaried in location. From this sector I employ two straps or hands 300301, which are passed over and fastened to dog-operating pulleys 91, oneof said bands or straps being a cross-strap and connecting with onedogoperating pulley 91 and the open band or strap connecting with theother dog -operating pulley 91. This construction and method of securingalternating movements of the clutch-dogs under many conditions ispreferred, in that I dispense with the use of connecting-rods 9 andobtain a more simple and cheap construction. Furthermore, in thismodification I employ two clutch-wheels 21 to provide room between forthe dog-operating pulleys 91. Many other changes may be employed asconvenience and conditions dictate, but further illustration thereof isdeemed to be unnecessary. The

features thus described are the features of especial novelty in themotor and transmitting means which I desire particularly to claim in thepresent case, and I do not deem it necessary to detail the constructionof the cooperating parts, such as the motor or engine proper and themeans therein for governing the movements of the same. All these partsand others connected with the vehicle may be such as are commonlyemployed. Peculiar adaptations of the same may be'made by me, especiallyin the motor, to be described in other applications.

In operating the device, power being applied to the motor by means ofexpansive air or gas, steam, combustible gas, or other powerproducingmedia, the pistons in the motorcylinders are driven and transmit powerto the oscillating shaft in any suitable manner. The oscillatingmovement of said shaft is transmitted to the rocking arm h, which inturn transmits its movements to the connecting-rodjand sector it, themovements of this sector being increased or diminished by adjusting thepin 71 with relation to the center of movement of the oscillating shaft.From the sector a in the construction first described power istransmitted by means of the ,belt or strap 3, looped over the loosepulley 6, and from said strap, the looped parts of which are caused tomove in opposite directions, the power is transmitted to theconnecting-rods 9, which are thus given alternating reciprocations. Saidconnecting-rods in turn alternately operate the dogs 26 26 to producethe forward continuous movement of the clutch -wheel 21, whichcontinuous movement is transmitted to the power-shaft 16 and from thenceto the sprocket-wheel 23 and chain or connections 25 and sprocketwheel251, applied to the axle of the vehicle. By operating the hand-wheel oand connections to bring the pin 11 in line with the shaft 6 the vehiclemay be made to stand at rest, the motor continuing to operate. Byoperating the hand-lever 0 the speed of the carriage is increased ordiminished, and by operating the hand shifting-levers 41 and connectionsthe direction of movement of the carriage is reversed, or the saidcarriage is caused to stand still while the motor continues inoperation.
